GREAT SUBS!

The following review is for SEXv2-12D4, which is a part of the bundle you are viewing.

Own 2 of this boyz wire at 1 ohm and let me tell you this subs have some serious power. Second battery recommended.. cracked my windshield on the 2nd day! Also have 1500 rms re audio amp which is good. I don't over power them or under power them.. i would recommend this to anyone that's serious about bass. Remind you again have a good electrical power on your ride for this babies ;)

RE-Audio-SEXv2-12D4

The following review is for SEXv2-12D4, which is a part of the bundle you are viewing.

Not a bad sub to have. It all depends on what you are going for. This sub has the tendency to be accurate at reproducing the lows you need, if you listen to rap/hip-hop a lot, then this is a good fit.

I would not overdrive these sub, or any sub for that matter. Give it between a 1/2 and 2/3 of the RMS power in a vented enclosure, you'll be happy all day.

Hard Hitting, Great Sound Quality

The following review is for SEXv2-12D4, which is a part of the bundle you are viewing.

One word... Impressed! I must say these subs not only pack a punch but the sound quality was very impressive as well. I've owned many brands of subwoofers except RE Audio, and I'm very happy with the decision of purchasing these SEXv2's. You won't be dissapointed!

The following review is for SEXv2-12D4, which is a part of the bundle you are viewing.

I had 2 p3 rockfords and they blew so I bought the re audio sex 12d4. They where out of stock so they upgraded me to the v2 for free. These subs bang hard an I'm glad I bought them. Sonic electronix always deliver on time. If buy these subs you your goin to need to souND deaden your trunk.

One of the best!

The following review is for SEXv2-12D4, which is a part of the bundle you are viewing.

I have 2 of these in seperate vented enclosures powered by a Hifonics BRX 1516 at 1 ohm with 4 gauge wiring and they sound almost too good! If i had a bigger enclosure I'm sure they would be even better but like myself and others say when we hear these subs "They are so loud and yet sound so clean" Definitely worth the $ if you want a higher end audio system in your car. I use to have two L7's and they were loud but not near as accurate or clear as these babies get! I can play hard hitting hip-hop all day and these never skip a beat or get hot. RE Audio is quality stuff.
